Double Drum New Road Roller

SEM 518 Soil Compactor road roller

Product Description(Road Roller)

Road Roller Vibe Pod Design

Eccentric vibe pod design, extends system life by 50%.

Steel shot moving inside closed eccentric block, stable and reliable.

vibe amplitude, reduces impact to motor, prolongs maintenance period of vibratory system.

Completely sealed eccentric gear eliminates contamination, prolongs bearing life.

Road Roller Cooling System

Isolated modular cooling system

Suction style fan pulls low temperature air through the radiator, providing superior cooling capability

Optional high ambient cooling system allows the machine to work in ambient temperature up to 50 ℃

Shunt tank provides constant system pressure and provides easy visual check of coolant level

Road Roller Vibratory Hydraulic System

Closed center hydraulic system

Improves efficiency by 20% over the open center system

Reduces oil contamination, prolongs life of hydraulic system
Maintains higher pressure and smaller energy loss
Allows for simpler hose routing
Requires smaller volume hydraulic tank, reduces maintenance cost

World class vibratory hydraulic components

SEM518/520 utilize Sauer piston pump and motor

Vibratory hose

Utilize Eton hoses and joints, high reliability
Optimized hose routing, prolongs hose life

Cat^® Product Link^TM

Cat® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management.

Powertrain

Electronically controlled transmission

Easier to shift, reduces operator fatigue and improves working efficiency
High reliability

Axle equipped with Proportional Torque differential (PTD)

PTD controls torque applied to the wheels based on ground conditions, improves overall traction
Grade ability is 34% compared to competitors` at 30%
Optimized transmission ratio, 1^st gear has higher travel speed

Dashboard

Vibratory Frequency Meter

Continuously displays machine compaction frequency

Operator may select appropriate frequency to avoid excessive compaction
